Tactics Advance is GBA, and Tactics Advance 2 is DS. If you have a 3DS, Fire Emblem: Awakening is not extremely punishing if you set the difficulty up right. Turning off permanent death helps. And it's got a great story with great characters. Unlike FFT which has mostly mindless cronies you throw away in battle and just a few actual legitimate characters

I'd almost suggest giving Shining Force 2 a look if you want to just enjoy the story and gameplay and feel accomplished without a huge amount of risk. The game can still kick your butt here and there if you don't pay attention, but in general getting a game over is fairly rare
